Just to add my 2c, "degree" implies some sort of graded scale. So
setting it to (say) 10 would be "maximum", setting to 0 would be
"none" and setting it to anything in between would be relative to the

eg in Vol26 "Encyclopedia of Computer Science and Technology" (the
first compsci reference that appeared for a google search) there are
three levels of granularity of degrees of parallelism.


Frankly it seems that the SQL crowd stole the computer science term
and applied it incorrectly.

Having a configuration option "_workers" makes much more sense to me.
It absolutely describes what it does without needing to refer to a
manual, and it removes ambiguity.
